Traditional droop control may cause problems such as station overload and increase in system loss with inappropriate DC voltage droop coefficient. In order to solve these problems

we proposed an novel droop control strategy

in which the system loss and station headroom are considered simultaneously to calculate the weighted average number of the droop coefficients after considering headroom of VSC and optimal power flow under minimum system loss respectively. Meanwhile

setting low-pressure acceleration factor makes VSC to emend the operation point dynamically. The available headroom is regarded as a main control target with relatively high DC voltage

and the minimum system loss is regarded as a main control target with relatively low DC voltage. Finally

we established a simulation model of five-terminal VSC-HVDC in PSCAD/EMTDC. The simulation results indicate that VSC can coordinate the control targets of available headroom and minimum system loss with novel droop control strategy according to the change of operation condition

and realize the dynamically corrected operating point. The expected performance of theoretical analysis verifies the effectiveness of the proposed strategy.
